mechanic47 · **87 shelby**

my 87 shelby z runs great,but every once in a while while driving it cuts completely out,the tach drops,and then it goes on just fine.It may do it again in a couple minutes,then maybe not for a couple days.there are no codes or any other problems.Its like the voltage is cut from the motor for a split second.Could the hall effect in the distributor cause this?thanks

Sounds like a classic HEP problem.
With the engine running wiggle/pull the wiring at the distributor and HEP connectors in an attempt to duplicate the problem.

Yeah, I had the same problem on my GTC. It was worse then I hot bumps. It was one to the two connectors going to the HEP on the distributor.
